197390-19-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197390-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,3,9 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 197390-19:
(8*1)+(7*9)+(6*7)+(5*3)+(4*9)+(3*0)+(2*1)+(1*9)=175
175 % 10 = 5
So 197390-19-5 is a valid CAS Registry Number.

Synthesis of bisindolylmaleimides using a palladium catalyzed cross-coupling reaction
Neel, David A.,Jirousek, Michael R.,McDonald III, John H.
, p. 47 - 50 (1998)
Bisindolylmaleimides are known to be potent and selective PKC inhibitors. A new synthesis of this class of compound is reported. The key step is a Suzuki cross-coupling reaction using a readily available indolylmaleimide triflate intermediate.
